What Is the 200-Day Moving Average?
The MA200 (200-day moving average) calculates the average closing price of a stock over the last 200 trading days — approximately 10 months of trading activity. It’s the most widely followed moving average in the world and serves as the definitive line between a long-term bullish and bearish trend.
When financial media says a stock or index is “above its long-term trend,” they’re almost always referring to the 200-day moving average.
Why Institutions Care About the MA200
The MA200 is not just a technical indicator — it’s a market structure benchmark. Here’s why:
- Pension funds and mutual funds often have rules about not buying stocks below their MA200.
- Algorithmic trading systems use the MA200 as a trigger for large buy/sell orders.
- Risk management teams at hedge funds use MA200 crossovers to adjust portfolio exposure.
- Media and analysts reference the MA200 when discussing market health.
Because so many participants act on the MA200, it becomes a self-fulfilling prophecy. When a stock approaches its MA200, large volumes of buying or selling kick in, making the level a genuine support or resistance zone.
The 200-day moving average is not just a technical tool — it’s a consensus mechanism. When price reaches it, the entire market takes notice.

Golden Cross and Death Cross
Two of the most watched events in technical analysis involve the MA200:
- Golden Cross — When a shorter-term moving average (like the 50-day) crosses above the MA200. This is considered a major bullish signal and often makes financial news headlines.
- Death Cross — When a shorter-term moving average crosses below the MA200. This is considered a major bearish signal. When the S&P 500 experiences a death cross, it’s front-page news on every financial outlet.
How Scanance Uses the MA200
Scanance calculates the MA200 for every stock across 10 markets and identifies signals based on proximity rather than crossovers:
- MA200 Buy — Price is within 1% above the MA200, and the MA200 slope is rising. The stock is sitting on institutional-level support.
- MA200 Short — Price is within 1% below the MA200, and the MA200 slope is falling. The stock is hitting institutional-level resistance.
This approach catches opportunities before a crossover event, giving you earlier entries. When a stock is within 1% of its MA200, institutional buying or selling is most likely to occur.
MA200 on Individual Stocks vs. Indices
The MA200 is powerful on both individual stocks and broad market indices, but it behaves differently:
- On indices (S&P 500, NASDAQ) — The MA200 is remarkably reliable as support in bull markets. The S&P 500 has historically bounced off its MA200 multiple times during bull markets before eventually breaking through at the start of bear markets.
- On individual stocks — The MA200 is a good filter for trend direction, but individual stocks can be more volatile. That’s why Scanance also checks the MA200 slope to ensure the trend is genuinely bullish or bearish.
Combining MA200 with Other Indicators
The MA200 is most powerful when combined with other signals:
- MA200 + MA150 — When price is near both averages, the support/resistance zone is extra strong.
- MA200 + RSI — An oversold RSI reading near the MA200 support is a high-probability buy setup.
- MA200 + MACD — A bullish MACD crossover while price is near the MA200 confirms momentum is shifting.
